Angels are forms, images and expressions through which the essences and energy forces of God can be transmitted; and, since there are an infinite number of these forms, the greatest service anyone can pay the angelic host is never consciously to limit the ways angels might appear to us.
When you slow yourself down and emanate peaceful, tranquil thoughts, you actually send the anxiety and stress out of your life. Similarly, when you meditate you bring God's silent love into your present moments. In silence and stillness God's energy will become yours. By slowing your mind and other thoughts, you allow the fastest vibrations of spirit to enter. That faster vibration is one of harmony, love, and peace.
